摘　　要：根据东濮凹陷黄河南地区的水分析资料,探讨了地层水矿化度的纵横向变化规律及其成因,阐述了它与黄河南地区沉积环境及油气分布之间的关系,指出,地层水矿化度较高的地区和层位有机质丰度高,油源充足,是有利的油气聚集区。提出了在该区地层水矿化度较高的层段寻找自生自储油气藏的思路,经过近两年的滚动勘探开发实践,取得了良好的效果,累积新增探明储量已超过1000×104t.Based on formation water analysis data from Huanghenan area in Dongpu sag, the salinity variation and origin of the formation water are discussed, and the relation of the formation water salinity to sedimentary environment and oil-gas distribution is expounded. It is pointed out that the area or zone with high salinity possesses high abundance of organic matter and enough supply of oil source. So it is favorable area for oil-gas accumulation. The authors proposed viewpoint that pools with both source and reservoir could be found in the zone with high formation water salinity. The rolling exploration/development practice in recent two years has gained outstanding effectiveness with incremental the cumulative proved reserves of over 1 000×104 t.
